[Pkg-zfsonlinux-devel] Bug#1032676: zfs-dkms: Installation fails on a Raspberry Pi 3 Model B+ (Raspberry Pi OS, 64-bit kernel activated)

[Wolfgang Liessmann]

Package: zfs-dkms
Version: 2.1.5-1~bpo11~rpt1
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Trying to install ZFS with "sudo apt -y install zfsutils-linux".


   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I also tried the following commands:

# https://wiki.debian.org/ZFS#Installation (March 10, 2023)

codename=$(lsb_release -cs);echo "deb http://deb.debian.org/debian $codename-backports main contrib non-free"|sudo tee -a /etc/apt/sources.list && sudo apt update

# Get keys for http://deb.debian.org/debian bullseye-backports InRelease (otherwise an error will occur)

gpg --keyserver hkps://keyserver.ubuntu.com --recv-key 648ACFD622F3D138
gpg --export --armor 648ACFD622F3D138 | sudo apt-key add -

gpg --keyserver hkps://keyserver.ubuntu.com --recv-key 0E98404D386FA1D9
gpg --export --armor 0E98404D386FA1D9 | sudo apt-key add -

sudo apt update
#sudo apt install linux-headers-amd64
sudo apt install -t bullseye-backports zfsutils-linux


   * What was the outcome of this action?

An error message claiming that loadable module support is not included, although the kernel supports it:

zfs-dkms (2.1.9-1~bpo11+1) wird eingerichtet ...

Error! Bad return status for module build on kernel: 5.15.84+ (aarch64)


   * What outcome did you expect instead?

Successful installation of the package in order to use the ZFS filesystem.
